Fix CJS require() returning empty namespace (#89)
Renamed the CJS bundles to .cjs so Node parses them as CommonJS instead of treating them as ESM under "type": "module".
main:dist/index.js→dist/index.cjsexports["."].require:./dist/index.js→./dist/index.cjsexports["./runtime"].require:./dist/runtime/index.js→./dist/runtime/index.cjs
require('oakscriptjs') now returns the full namespace (81 exports) again. ESM consumers are unaffected.
